Acceleration is the rate at which an object changes speed.
Velocity is a combination of speed and direction

What is the definition of non uniform motion in physics?
During uniform motion, velocity is constant, so there is zero acceleration. Non-uniform motion involves a change in velocity, which means there is acceleration. Accelaration is a change in velocity. A change in velocity occurs when a body slows down, speeds up, or turns (changes direction), or a combination of these.
Does a change in direction change acceleration?
Not exactly, it can change a few degrees of its direction, but cannot change its velocity because if it stops, the force of motion that goes with it will demolish the car therefore it cannot change it's velocity.++++???? If you put the question in everyday language, it is asking "Can a car change direction while accelerating?"Yes it can, provided the driver is careful to keep the acceleration and instant speed within safe limits. I emphasise 'speed' because the direction hence velocity - a vector value - is changing.I have no idea of the point about the remark about stopping - the supposed consequences are fiction, and the question is about accelerating.
Is it true or false that acceleration can only occur when the speed of an object changes?
No. Acceleration is change of velocity. It occurs when an object changes speed and/or direction.
The rate of change of an objects position is?
Acceleration occurs when the velocity of an object changes. Velocity is the speed and direction of an object. Newton's Second Law of Motion defines what happens when a force acts on an object. The object accelerates in the direction in which the force is acting. A force acting on a stationery object starts it moving. A force acting on a moving object will speed it up, slow it down, or change the direction in which it is movingDefinition of deceleration: (physics) a rate of decrease in velocityDefinition of acceleration: (physics) a rate of increase of velocityProps to Google :)
When does zero acceleration occur?
Zero acceleration occurs when a body's velocity is constant. Newton's First Law of Motion tells us that this occurs when the external forces acting upon a body are balanced.

What is the rate of change of velocity which occurs if an object speeds up changes direction or slows down?
Any change in velocity, whether to speed up, slow down, or just change direction, results from acceleration. Acceleration is an expression of the rate of change of velocity.
Is it true or false that acceleration can only occur when the speed of an object changes?
No. Acceleration is change of velocity. It occurs when an object changes speed and/or direction.

What types of change in motion causes acceleration?
Motion is the change of position over time. The rate of change of position is called or speed. Speed combined with its direction is called velocity. The rate of change of velocity is called acceleration. So, motion in which the speed or direction are changing is accelerated motion. The question uses the word cause, which may be confusing. Technically when a force is applied to a mass, there is acceleration. When there is acceleration the velocity changes. If the object was in motion to begin with, it would speed up or slow down or change direction. If the object was at rest, the force would have caused an increase in speed from zero, so it would start moving. Therefore if you think of a causal relationship, it would be more proper to say force causes acceleration, which IS a change in motion. For an example, an easy one is your bicycle. If you pedal, you are applying force. That force cause the bicycle's speed to increase ... acceleration ... and you are in motion. If you apply more force, you will go faster. If you apply the brakes, you will slow down which is also acceleration (because speed is changing). There is only one way to have motion without acceleration and that is to travel at a constant velocity ... constant speed in a straight line. In practice, there is no motion without acceleration for any period of time, because there is always some minute change in speed or direction.

When an object's speed changes it velocity also changes?
Acceleration, the change of velocity, occurs. DO NOT EVER CALL IT DECELERATION. That term is for the archetypal caudex ( it's latin, look it up)...Hence, acceleration includes both the increase AND decrease in the rate of change in velocity...and there you have it.
When speed changes does its velocity change?
When the object is acted upon by an outside force.
Motion occurs when there is a change in?
acceleration
What happens when two balanced forces are acting on an object?
No acceleration occurs - if stationary, it does not move, if moving, it continues its original velocity (speed *and* direction).
Can acceleration and velocity be the same?
No. Velocity is the change of location and accelarion is any change that occurs to the velocity of an object.
